Specification of Letters Patent.

Application led December 20, 1815. Serial No. 67,869.

To all 'whom t may concern:

Be it known that 1, ALFRED Coronr, subject to the Emperor of Austria, residing at Chicago, in the county o1?l Cook and State of Illinois, have invented new and useful Improvements in Railway-Car-Roof Construction, of which the following is a full, clear, concise, and exact description, reerence being had to thev accompanying. drawforming a part of this specification.

l y invention relates to railway car roof construction. i

Amon the objects of my inventlon are to provi e such a construction whlch Wlll be simple, eicient durable and yieldin t'o accommodate itself to the racking of t e ca r; one which will be leak proof and which wlll eiiectually keep out cinders; and to provide an improved construction using a one-place sheet metal roof without the usual supporting carlines and purlins, and 1n which means are provided for 'draining .o the moisture which condenses on the inside of the roof.

Further objects will appear from the f ollowmg description taken 1n connection w1th the appended claims.

In the drawings, in which I- have shown two embodiments of my invention- Figure 1 -is a plan view of partof a car roof showing my improved construction;

Fig. 2 is a transverse section of the upper part of the car;

Fig. 3 is a detail of the connection between the edge of the roof and the side of the car;

Fig. 4 is a side elevation of part of the upper part of the car;

Fig. 5 is a detail of the running board and support;

Fig. 6 is a detail of the modification of the connection between the roof. and side of the car;

Fig. 7 is a perspective view showing an end construction which Fig. 8 is a detail of a still further modiication of the connection between the roof and side of the car.

Referring now to the drawings in detail, and first to the form shown in Figs. 1 to5, l have here shown my invention in connection with a car comprising the posts 10 forming part of the side construction, and braced in any suitable manner, Z-bar side plates 11 forming a connection between the side construction and the roof, angle clips Eatented Nov. 6, 1917.

tending from one side of the carto the other -to revent the side plates from spreadin,

eet metal roof 14 attached at its sie edges to the upper vertical webs of the Z- bar, tie plates 15 extending transversely of the car and having their ends suitably secured to the sheet metal roo` 14, as by spot welding, the running board 16 extending along the top of the car, and cli s 17 for supporting the running board an securing it to the car roof. The tie rods 13 may have their ends secured to the side construction by being threaded, as shown at 18, and provided with nuts 19 on opposite sides of the lower flange of the side plates 11.

The car roof 14 may be made of sheet metal sections 2O suitably secured together at their edges 21 as by butt welding. Each section 20 is provided with one of the tie plates 15. The tie rods 12 also assist in preventing buckling of the car roof. The clips 17 may be sections of angle iron `secured ,to the car roof, bolts 22 extending from the clips 17 on one side of the running board, and other bolts 23 extend across beneath the running board. The side edges of the sections 20 are bent inwardly and upwardly to form channel portions 24 and are portions 25, the latter of which channels receive the upper vertical web of the Z-bars 13 to which they are suitably secured, means of bolts 26. The l channel 24 is provided apertures 27 to permit drainage of any moisture which may .condense on the inner surface of the roof and run down into the channel 24. A wood ller 28 is rovided on top of the middle web of the bar beneath the channel portion 24 to prevent as by ower'part of the with a number of wearing contact between metal and metal. may be used; and

It will be noted that in this construction there are none of the usual carlines and purlins for supporting the roof; that the upwardly bowed shape of the roof, and also the channel portions 24, make the roof yielding to accommodate itself to the racking of the car, and that the entire car roof is one integral piece of sheet metal supported solely at its side edges.

In the modification of Fig. 6, beams 11, the tie rods 12 and the Z-bars 13 are the same as in the construction of Figs. lfto 5. The roof 29, however, it not provided with the channel portions 24 and 25, but has its vertical edge portion 3() suitably secured directly to the vertical flange of the Z-bar 13 as by bolts 31. l

ln Fig. 7 I have shown an end late construction which ma be used, in w ich provision is made to a low the end plate to expand and contract slightly to permit some springing of the roof 14. 'In this construction the end plate 32 is secured to the roof 14 in any suitable manner, and this end plate is rovided with tapering corrugations 33 ormed therein by stamping or in any suitable manner. These corrugations will allow the end plate to spring somewhat so that the whole roof construction is a yielding vone which will accommodate itself to the racking of the car.

In the modification shown in Fig. 8 the roof 34 is provided with a channel portion 35 and an inwardly extending flange p0rtion 36 which rests on a longitudinally extending beam 37 to which it is secured by means of bolts 38. Channel portions 35 be provided with drawn openings 39.

m avmg thus described my lnvention what I claim as new and desire to secure by Letters Patent is 1. A railway car comprising side construction for the two sides of the car and an upwardly-bowed springy sheet-metal roof extending from one end to the other of the car and from one side to the other thereof and supported solely adjacent its side edges by said side construction, all the vertical longitudinal sections of a substantial portion of said sheet-metal roof being bounded by substantially straight horizontal lines and all the vertical transverse sections of said sheet-metal roof being substantially identical and bow-shaped whereby the edges of said roof can spring toward each other to accommodate the racking movement of the side construction of the car.

2. A railway car comprising side construction for the two sides of the car and an upwardly-bowed springy sheet-metal roof extending from one end to the other of the car and from one side to the other thereof and supported solely adjacent its side edges by said side construction, all the vertical longitudinal sections of said sheet-metal roof being bounded by substantially straight horizontal lines and all the vertical transverse sections of said sheet-metal rootl being substantially identical andbow-shaped whereby the edges of said roof can spring toward each other to'accommodate the racking movement-of the side construction of the car.

3. A railway car comprising side construction for the two sides of the car and an upwardly-bowed springy sheet-metal roof extending from one end to the other of the car and from one side to the other thereof' and supported solely adjacent its side edges by sal side construction, all the vertical longi tudinal sections of a substantial portion of said sheet-'metal roof being bounded by substantially straight horizontal lines and all the vertical transverse sections of said sheetmetal roof being substantially identical and bow-shaped whereby the edges of said roof can spring toward each other to accommodate the racking movement of the car, said roof comprising upwardly-bowed sheetmetal plates extendin from one side to the other of the car, a jacent edges of said plates being butt-welded together.

4. A railway car comprising side construction for the two sides of the car, and a self supporting roof comprising an integral upwardly bowed sheet metal plate extending from one side to the other of said car and supported solely adjacent its side edges by said side construction, said side edges being bent inwardly and upwardly to form a channel, said channel portion being secured to said side construction to support the roof.
